Mould Remediation Services in Winnipeg
Comprehensive Mould Removal for Basements, Attics, Crawlspaces, and More
Mould is common in Winnipeg, particularly in basements, crawlspaces, attics, and near plumbing, and it spreads fast when moisture is present. Relief Restorations provides certified mould remediation that removes mould safely, restores healthy air quality, and prevents future growth.
Whether you’re noticing musty odours or visible mould, our Winnipeg team responds quickly with professional solutions you can trust.
Mould is one of the most common issues affecting Winnipeg homes due to high humidity, seasonal temperature swings, and moisture intrusion from basements, attics, and crawlspaces. When mould appears, it can spread quickly, affect indoor air quality, damage building materials, and pose health risks, especially for individuals with allergies, asthma, or sensitivities. Relief Restorations provides professional mould remediation across Winnipeg and surrounding communities, using industry-approved methods that remove mould safely and prevent it from returning.
Why Mould Forms in Winnipeg Homes
Winnipeg’s climate creates ideal conditions for mould growth. Sudden freeze-thaw cycles, summer humidity, and poor ventilation often trigger moisture buildup behind walls, under flooring, in attics, and inside basement cavities. Common causes include:
• Water leaks, plumbing failures, and slow drips
• Foundation seepage and basement flooding
• Poor ventilation in bathrooms, kitchens, and attics
• Condensation on exterior walls and cold surfaces
• Attic insulation problems and ice damming
• Moisture migration from crawlspaces or slab-on-grade foundations

Attic Mould Removal
Winnipeg attics often develop mould due to poor ventilation, bathroom fan exhaust issues, and winter condensation. We remove attic mould safely and provide solutions for airflow, insulation, and humidity problems. This prevents future growth and protects your roof structure.
Basement Mould Removal
Basements are one of the most common areas for mould in Winnipeg because of humidity, seepage, and past water damage. We remediate mould found behind drywall, on foundation walls, and in cold corners. After cleanup, we provide moisture correction strategies tailored to your home.
Crawlspace Mould Remediation
Crawlspaces often trap humidity and stale air, allowing mould to spread quickly. We remove contaminated insulation, clean structural wood, improve airflow, and address moisture sources. This helps protect your home’s air quality and prevent mould from rising into living spaces.
Bathroom, Kitchen and Laundry Room Mould
These areas frequently develop mould from shower steam, poor ventilation, and plumbing leaks. We remove surface and hidden mould, correct moisture problems, and offer recommendations for proper ventilation. This keeps high-humidity rooms clean and mould-free long-term.
Post-Flood or Sewage Backup Mould Cleanup
After water damage, mould can begin growing within 24–48 hours. We provide rapid response to remove affected materials, disinfect the area, and dry the structure. This prevents further damage and accelerates safe reconstruction.
Our Mould Remediation Process
Our Winnipeg Mould Remediation Process We follow industry-standard procedures, including IICRC S520, to make sure mould is removed completely and safely. Our process includes:
Step 1:
Inspection & Source Identification
We begin with a detailed inspection to assess visible mould, hidden moisture, odours, and air quality concerns. Using moisture meters and thermal imaging, we locate mould behind surfaces and identify the root cause, whether it’s seepage, condensation, ventilation issues, or attic humidity.
Step 2:
Containment, Protection & Safe Removal
The affected area is fully contained with poly barriers, negative air pressure, and HEPA filtration to prevent cross-contamination. Contaminated building materials such as drywall, insulation, vapour barriers, and baseboards are removed and disposed of according to Manitoba regulations.
Step 3:
Cleaning, Air Filtration & Decontamination
We perform thorough cleaning using HEPA vacuuming, antimicrobial agents, and scrubbing techniques to remove mould from structural materials. Air scrubbers operate throughout the process, followed by full decontamination to restore a safe indoor environment.
Step 4:
Moisture Correction, Prevention & Final Documentation
We identify the exact moisture issue, such as foundation seepage, attic condensation, ice damming, or poor ventilation, and provide clear prevention recommendations. Before-and-after photos, moisture readings, and a written report complete the project, ensuring you have full documentation for your records.

Frequently Asked Questions
What is Mould?
Mould is a fungus consisting of small organisms. In minute amounts may be harmless; however, it can still be dangerous. Once mould finds a good spot to sit, such as a damp area, it will start to grow. Mould spores can be released into the air, where they can be inhaled, causing health issues.
How To Remove Mould?
Mould should not be taken lightly; mould will release spores into the air, causing health issues. If you have mould in your building or home, give us a call to make a removal plan. Certain types are not that dangerous; however, there are certain types that can cause major health concerns and should only be removed by a trained and certified professional. Rooms with mould need to be treated and contained properly.
What Are Common Areas For Mould Growth?
Mould typically forms in cool, humid/damp, dark areas of buildings or near heating/cooling appliances such as:
-
Basements
-
Showers
-
Refrigerator
-
Carpets
-
Ventilation Ducts
-
Crawlspaces
-
Walls
-
Attics
-
Windows
-
Bathrooms
Why Is Mould Dangerous?
Some people are more sensitive to mould than others; mould exposure can lead to symptoms such as a stuffy nose, wheezing, and itchy or red eyes and skin. Severe reactions can occur, which may include fevers or shortness of breath. People with weak immune systems or asthma are particularly prone to reactions and infections from mould. Continuous exposure can lead to further problems down the road.
I Have Allergies/Asthma; Am I at a Greater Risk?
If you have allergies or asthma, your immune system can overreact to inhaled mould spores, causing a more intense reaction. A reaction can cause coughing, itchy eyes, chest tightness, etc. It can also restrict breathing. At times there may be a delayed reaction to these symptoms.
I Can't See Mould, Can I Still Have Mould in My Home?
Yes, mould is commonly found behind walls and in dark, damp areas we tend to not see. If mould is not visible, we may need to test for the presence of mould using air testing methods or opening up walls and other areas prone to mould growth.
How is Mould Removed from My Home/Building?
We remove mould in a similar fashion to asbestos. We often set up a containment work area to eliminate contamination to the rest of the building. We use specialized filtration and/or air movement to remove the airborne mould spores while we're completing the remediation process
Can I Stay in My Home/Building While the Remediation is Taking Place?
No, under most circumstances, all occupants are required to vacate the home during the remediation process to ensure everyone stays safe and healthy during the process. We lock all doors when we leave and make every effort to keep the building safe during this period. For large buildings, occupants are not allowed in or around the work area.
Do You Use Safe Products in the Removal Process?
Most of the time, the products we use are completely safe and aren't any more harmful than vinegar. The products are very eco-friendly. On the rare occasion we need to use something stronger, we ensure a thorough cleanupprocess is completed afterwards.
